Laser Scanning

SES was one of the first Land and Engineering survey companies to purchase a High Definition Surveying Laser Scanner (Leica HDS 3000) within the UK. With our experience using the HDS 3000 for capturing point cloud data we have been involved in many innovative projects throughout the UK. It has never been easier to survey elevations, facades, topography, as-builts and engineering structures. HDS is a portable 3D laser scanner which supports standard surveying procedures, such as instrument setup over a known point, height-of-instrument measurement, and instrument orientation. With the scanner acquiring up to 1800 points per second and to an accuracy of +/-6mm over a 50m range. Any exposed surface can be remotely captured in minutes to form a dense, accurate "3D points clouds"

Undoubtedly the amount of detail that the Laser Scanner obtains is a direct benefit to the Project's Designers. At 1800 points per second, HDS covers a larger area in less time and to greater detail than conventional survey techniques. What this means is we can extract more design information than before, ensuring confidence within the design team.

A whole range of products can be interrogated from the 3D point cloud, 2D plans, Elevations, Sections to complicated 3D Models/Visualisations. 3D point cloud information can be imported into various Computer Aided Drafting packages.

There are a wide variety of uses that 3D laser scanning can be effectively employed including:

Elevations
As-built surveys for engineering and construction projects
Topographic surveys
Rights of light
Building surveys
Bridges, roads, tunnels, quarries and railways
Archaeological sites
Accident investigation
Heritage buildings and artefact archives
Monitoring land deformation

From a safety point of view the instrument can be set up remotely in an area away from hazards. As it uses a non contact (class 3R laser) survey technique it is ideal for surveying inaccessible and potentially dangerous areas e.g. roads, rail and high rise areas.

The Leica HDS3000 is a versatile, multi-purpose scanner that combines high efficiency with high accuracy for a broad range of civil engineering, plant and building projects. At the forefront of innovation in surveying, SES continues to harness the latest technology for the benefit of our clients in providing solutions to the seemingly impossible.
